MEANS FOR APPLYING GARNETT OB LIKE WIRE TO ROLLERS OR CYLINDRIGAL SURFACES.

Application filed March 9,

To all whom it may concern: j

I Be it known that I, JAMES DRoNsFIEm), a subject of the King of Great Britain and Ireland, residing at the Atlas Works, Oldham, in the county of Lancaster, England, have invented new and useful Improvements in and Relating to Means for Applying Garnett or like Wire to Rollers or Cylindrical Surfaces, of which the following is a specification.

This invention has reference to improve ments in and relating to means for applying Garnett or similar wire to rollers or other cylindrical surfaces which are cut with a spiral groove or channel for the reception or thrusting-in of such wire, while such rollers or the like ar in position in the waste opener or the like.

The improvements follow a previous invention for which I have obtained Letters 1 Patent No. 1,173,492, February 29th, 1916,

and to which the reader can refer.

In certain classes of machines such as waste openers, by way of example, it would represent a convenience to provide means capable of being readily applied to the frame-work whereby a roller or cylinder could be clothed or re-clothed in position and without'the necessity of removing such roller 0r cylinder, and my invention aims at accomplishing this result.

According to my invention I provide readily attachable and detachable mechanism to this end, and the drawings annexed illustrate a suitable construction which I propose to make use of. r

In the said drawings Figure 1 shows an end elevation of the attachable and detachable combination.

Fig. 2 is a plan of the traversable carriage and detachable holding-up stay.

Fig. 3 shows a longitudinal view ofthe mechanism broken as to length and the same being illustrated as applied to the side frames of a waste opener.

Figs. 4 and 5 are views indicating the wire carrying reel which is supported on the traversable carriage.

Figs. 6 and 7 are side and end views of the auxiliary carriage.

Figs. 8 and 9 are views of the angularly Specification of Letters Patent.

adjustable bracket which supports the rolling-in wheels.

- Fig. 10 is a view of a detachable element of the last mentioned bracket such element belng shown in position in Figs. 2 and 9.

I provide a bed casting or shears a and the same is adapted to rest on or span the side frames-A- A of'the waste opener or the like and to be readily clamped or bolted thereto by detachable means, as for example clamping brackets b, b and bolts 6 screw threaded longitudinal shaft 0 is supported by such bed casting or shears a and works in suitable bearings and is actuated by a crank or handle applied to its shaped extremity, or by a pulley as may be desired. Such bed casting is shaped for the reception of a traversable carriage d and planed blocks a? and anti-friction rollers d may be projections 03 d on the, bed casting a. suitable brackets or bearings e, e attached to the traversable carriage d is a short shaft 6 with operating hand lever 6 and such upported in shaft e carries a pinion e cut with teeth to engage the screw thread cut on the longitudinal shaft 0. A wing-nut clamping device c" is fitted, by unclamping which, the pinion 6 can effect longitudinal movement of the traversable carriage (1 when the hand lever e is turned, while, by clamping-up the wing-nut device 6 the screwed shaft 0 acting on the pinion 6 can become the driver and traverse the carriage d. The traversable carriage d is fitted with an auxiliary carriage g adjustable'at right-angles to the di i are similar to and act like those described in my former patent, and, said bracket 72.. is angularly adjustable about the point hto get the correct angle or disposition of the rolling-in wheels 71 to the groove in the roller t9 be e th i- 1 he g 3 sted? bracket it is formed with a curved concentric slot 7& and any desired angular ad ustment is retained by screwing-up the clamping bolt at 7L3. The bracket 72 also carries the adjustable clamp or guide j fixed in the planed recess 7'', see Figs. 8, 8 and 9, and through which clamp or guide 7' the wire to be rolledin passes. The traversable carriage (Z carries or may carry the supporting means for the reel supplying the wire to be applied. In the drawings a socket hole is provided in the carriage at the point (Z and a bar 01 is fixed therein such bar carrying a bracket (Z which in turn has an axle (Z upon which the reel (Z is supported.

Sets of gear wheels are provided to be applied to the screw threaded shaft 0 and to the roller 1" in which the wire requires to be applied, whereby the carriage is traversed at a speed suitable to the pitch of the groove into which the wire requires to be thrust. The gear wheel applied to the roller 1* to be clothed is constant, the wheel is being the change wheel and this is applied to the screw threaded shaft 0.

In the case of small diameter rollers it is necessary to apply means to prevent the roller sagging under the pressure from the rolling-in wheels and I apply means to this end. I use in the construction shown, a holding-up stay or slide Z with bent or cranked extension Z with removable block Z to hold up the roller 1" from the back, such stay or slide Z being slotted at Z Z and secured by studs or bolts Z Z to an other slide on mounted on the traversable carriage (Z. Said slide m is slotted at m, m and held to the carriage by studs m m This second slide m is arranged for adjustment by a screw threaded device m or other equivalent. The slots Z Z provide for a considerable adjustment and the screw device m for a finer adjustment, as is obvious. In case the rollers to be covered are of considerable diameter and sufficiently rigid, the stay or slide can be easily detached by removing the studs Z Z.

In use, the mounting attachment is lifted and secured in place on the waste-opener or thelike, as indicated at Fig. 3 and the traversable carriage d is set exactly to position by operating the hand lever c with the wing-nut clamp 6 released. This done, the wing-nut clam-p e is turned to secure the setting. The holding-up stay Z is set to the roller 1" as required and thereafter the rolling-in wheels 1 are set to the angle of the spiral or groove in the roller to be clothed and adjusted or advanced to do their work. The wire is of course led from the reel cl through the clamp j and delivered to the rolling-in wheels. From this, it is seen that as the screw shaft 0 is turned, the traversable carriage d is moved along and the rolling-in wheels '5 insert the wire into the grooved roller 1" which is rotated due to the action of the chain k and chain wheels 7a, 70 at a speed to suit the speed of travel of the traversable carriage.

Obviously considerable detail modification is possible without departing from the main idea which is a readily attachable and detachable wire mounting apparatus for application to waste openers, &c. for the purpose of laying clothing or laying fresh wire with the roller or the like in situ.

I declare that what I claim is:

1. An attachable and detachable apparatus for applying Garnett or L-shaped or like wire to the rollers of opener and other machines when the roller is in position, comprising a fixable support, means to secure the support to the framework of t 1e opener, a traversable carriage on said support, gear on the traversable carriage, means on the support for engaging the gear on the carriage to traverse the carriage, and driving gear for driving the roller in conjunction with the carriagemovement, rolling-in wheels on the carriage and means for setting the rolling-in wheels and guiding means for the wire to be rolled-in. V p

2. In an attachable and detachable apparatus for 'the'indicated purpose, a movable carriage, rolling-in wheels on said carriage, an adjustable or removable stay adapted to be carried by the carriage, a slide on the carriage, means which permit the stay to be adjusted on the slide to support or back-up rollers of varying diameter while the rolling-in wheels perform this oflice. y

8. In an attachable and detachable apparatus for the indicated purpose, astay,

a backing-up portion on said stay, slots in said stay and a traversable carriage, roll- 7 ing-in wheels carried by said carriage, a slide on the carriage and means for fixing the stay in an adjusted .position the stay backing-up the roller to be clothed and' moving with the traversable carriage.

4-. An attachable and detachable apparatus for the purpose indicated comprising a bed casting, an operable shaft supported in the casting, a traversable carriage movable on the casting, gear on the carriage engaging the operable shaft and by which the carriage can be traversed, a bracket on said carriage, means to adjust the same, an angularly adjustable bracket, means to adjust same, rolling-in wheels on said angularly moving on the casting, gear on the carriage engaging the shaft and means to operate the carriage traversing gear, an adjustable bracket on the carriage, adjusting means therefor, and an angularly adjustable bracket, means to adjust same, rolling-in wheels on the angularly adjustable bracket,

gear to drive the roller to be c1othed,vand a stay on the carriage to back-up the roller, and means which permit adjustment of the 10 stay.

In testimony whereof I have signed my name to this specification.

JAMES DRONSFIELD.
